Is there a way to do cloze deletions and <input> inside of code blocks?

I've been trying to figure out how to do cloze deletions and input blocks inside of code snippets.

For example:

I can't get them to work inside of code fences.

I can't tell if it's not possible, or if there's some formatting trick that will make it work?

Unfortunately it's not possible. Cloze deletions inside of code blocks has not been implemented yet.
